  • question_answer In the case homologous series of alkanes, which one of the following statements is incorrect?    [JIPMER 2000]

    A) The members of the series are isomers of each other

    B) The members of the series have similar chemical properties

    C) The members of the series have the general formula\[{{C}_{n}}{{H}_{2n+2}}\], where n is an integer

    D) The difference between any two successive members of the series corresponds to 14 unit of relative atomic mass

    Correct Answer: A

    Solution :

    The difference between any two successive members of the homologous series \[-C{{H}_{2}}-\] i.e., the molecular weight of every two adjacent members differ by 14. \[(C{{H}_{2}}=12+2=14)\]
